As you already guessed it's a Tetris clone, positive is the team mode, negative is that sometimes when you move down a block, the game moves down the next one too without your intention.

The cracker group Genesis Project spread 
the game already in January 1990 
before its official release date

Comment:
the 2nd bomb also disappears in the original version

Game On 1991/02, Game On GE 1992/2, Abo Disk #3
